AC Power SPD surge protection device



The ac power surge protection device is designed to prevent transient surge conditions. Large single surge events, such as lightning, can reach hundreds of thousands of volts and can cause immediate or intermittent equipment failure. However, lightning and power anomalies account for only 20% of instantaneous surges. The remaining 80% of the surge activity is generated internally.

Our AC power SPD surge protection device, also called AC surge arrester or AC surge suppressor, supports long-term system reliability by absorbing large amounts of transient energy while maintaining low clamp voltages.

Our type 2 AC surge protector SPD can provide high-quality, safe and reliable surge protection for devices in power supply circuit systems.

The surge protector for AC compressor is widely used in petrochemical, gas, environmental protection and new energy industries.

CHENZHU, a reliable company in safety and automation system, also provide various other surge protectors to meet the needs of our customers, such as mini split voltage protector. For the price of AC SPD surge protector and other related information, please feel free to contact us.
